Description

The invention relates to the treatment of parts by surface plastic deformation and can be used in the processing of metal parts of any shape. The purpose of the invention is to improve the quality of processing. The method of surface plastic deformation consists in the fact that the treatment is carried out with an instrument with an indicator in the form of a light concentrator when a light beam is applied to the surface to be treated, which is directed to the zone, the instrument-through-indenter contact is chosen, and the force of plastic deformation is selected depending on the purity the treated surface, while in the process of processing, the cleanliness of the treated surface is monitored, the latter being produced in intensity evogo flux reflected from the workpiece in the processing zone. . The method of surface plastic deformation can also be carried out with the supply of coolant to the treatment zone, while the latter is used as an immersion liquid with a refractive index equal to the value of the refractive index of the indenter material. Figure 1 shows an instrument for surface plastic deformation, a general view; in FIG. 2, the element I in FIG. on fig.Z - element II in figure 1. The tool consists of an indenter in the form of a light concentrator 1, made of translucent material, such as cubic zirconia, diamond, etc., whose front surface 2 can be flat, spherical, or some other shape. The light concentrator 1 is fixed on the holder 3 with an opening 4 for the passage of the beam of radiation 5; the light concentrator 1 is made with a light-guide face 6 located at the light receiving; multiple 7. surfaces 1. The light exit face 6 is in contact with the end of the light guide 8. A photo-converter 9 is fixed on the holder 3 to receive the light beam reflected from the surface being treated 10. In the hole 4 of the holder 3, a translucent core 11 can be inserted, and the light concentrator 1 can be made in the form of a tapered lens, conical or prismatic. As the coolant can be used a solution of glycerol in water. A diamond layer can be applied to the working surface of the indenter, for example, by methane pyrolysis. The processing of parts by the proposed method is performed as follows; The described tool is fixed on the support of the machine and guided to the workpiece surface, pressing with the force required for surface plastic deformation. The rotation of the part is turned on, and the tool is set to axial flow. The light beam 5 is directed to the light concentrator 1 in the form of a laser beam that heats the part in the zone of contact with the tool. The light beam flux 10 is detached from the irregularities of the machined surface of the part and falls on the light emitting edge 6 and through the light guide 8 to the photovoltage converter 9 associated with an analyzer (not shown) that processes the signals from the photovoltage converter 9. The surface of the processed surface is judged by the signal and adjust the pressing force of the tool and the part. Processing can also occur when the coolant is subjected to surface plastic deformation. Controlling the surface finish in the plastic deformation zone and controlling the pressing force of the tool improves the quality of the treatment.
